wcsGetCoverage.xsd 2010-02-01 http://schemas.opengis.net/wcs/1.1.0/gml4wcs.xsd This XML Schema Document defines the GetCoverage operation request elements and types, for the OGC Web Coverage Service (WCS). WCS is an OGC Standard. Copyright (c) 2006,2010 Open Geospatial Consortium, Inc. All Rights Reserved. To obtain additional rights of use, visit http://www.opengeospatial.org/legal/ . Request to a WCS to perform the GetCoverage operation. This operation allows a client to retrieve a subset of one coverage. In this XML encoding, no "request" parameter is included, since the element name specifies the specific operation. Identifier of the coverage that this GetCoverage operation request shall draw from. Optional selection of a subset of the coverage's range. Asks for the GetCoverage response to be expressed in a particular CRS and encoded in a particular format. Can also ask for the response coverage to be stored remotely from the client at a URL, instead of being returned in the operation response. Optional definition of the GridCRS in which the GetCoverage response shall be expressed. When this GridCRS is not included, the output shall be in the ImageCRS of the stored image, as identified in the CoverageDescription. Identifier of the format in which GetCoverage response shall be encoded. This identifier value shall be among those listed as SupportedFormats in the DescribeCoverage operation response. Specifies if the output coverage should be stored, remotely from the client at a network URL, instead of being returned with the operation response. This parameter should be included only if this operation parameter is supported by server, as encoded in the OperationsMetadata section of the Capabilities document. Definition of the desired subset of the domain of the coverage. Contains a spatial BoundingBox and optionally a TemporalSubset. Definition of desired spatial subset of a coverage domain. When the entire spatail extent of this coverage is desired, this BoundingBox can be copied from the Domain part of the Coverage Description. However, the entire spatial extent may be larger than a WCS server can output, in which case the server shall respond with an error message. Notice that WCS use of this BoundingBox is further specified in specification Subclause 7.5. Optional definition of desired temporal subset of a coverage domain. If this data structure is omitted, the entire Temporal domain shall be output. Definition of subset of coverage temporal domain. Selection of desired subset of the coverage's range fields, (optionally) the interpolation method applied to eachfield, and (optionally) field subsets. Unordered list of one or more desired subsets of range fields. TBD. Identifier of this requested Field. This identifier must be unique for this Coverage. Optional identifier of the spatial interpolation type to be applied to this range field. This interpolation type shall be one that is identified for this Field in the CoverageDescription. When this parameter is omitted, the interpolation method used shall be the default method specified for this Field, if any. Unordered list of zero or more axis subsets for this field. TBD. List of selected Keys for this axis, to be used for selecting values in a vector range field. TBD. Identifier of this Axis. This identifier must be unique for this Field. Unordered list of (at least one) Key, to be used for selecting values in a range vector field. The Keys within this list shall be unique. TBD.
